Castello della Valle (Fiumefreddo Castle), founded in 1201, was the residence of the noble lords. During the mid-16th-century, the castle was donated to Ferdinando De Alarçon-Mendoza, marquis of the Valle, and took its current name of Castello della Valle. The current appearance dates from that age. The castle was besieged in 1806-1807 by French troops and nearly destroyed. Today it houses several works of local painter Salvatore Fiume.
Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
